2 MINIpowerUPS SYSTEM DESCRIPTION Using a unique modular construction, the MINIpowerUPS model range represents a completely new generation of low power single-phase UPS systems that incorporate the latest technological developments in power engineering. High reliability, upgrade ability, low operating costs and excellent electrical performance are just some of the highlights of this innovative UPS solution. This system s advanced double conversion Voltage and Frequency Independent (VFI) topology fully satisfies the highest availability and environmentally-friendly requirements compliant with the most stringent safety, EMC and other important UPS standards. It is certified to International Standard ISO 9001/EN and ISO The MINIpowerUPS is a truly modular system based on 1250VA power modules. Depending on the model, the MINIpowerUPS cabinet can contain up to four or eight power modules operating in parallel to provide a 5kVA or 10kVA rated UPS system. MINIpowerUPS 5000 model range The MINIpowerUPS 5000 is available in both Rack-mounted and Tower versions and uses up to four 1250VA power modules to offer a system output rating of 1250VA, 2500VA, 3750VA or 5000VA. Each power module requires three batteries which are housed within the UPS cabinet to provide a completely selfcontained UPS system. An optional external battery cabinet can be connected to the UPS to extend the system s autonomy time if required. MINIpowerUPS model range The MINIpowerUPS is available in a tower version only and uses between four and eight 1250VA power modules to offer a system output of 5000VA, 6250VA, 7500VA, 8750VA or 10000VA. In this model range the batteries are contained in a separate battery cabinet which is similar in design and appearance to the UPS cabinet and is usually positioned adjacent to the UPS cabinet to form a matching suite. If required, additional battery cabinets can be connected to the existing battery cabinet to extend the system s autonomy time. System expansion Thanks to the advanced MINIpowerUPS system design, if a cabinet is not fully populated with power modules when purchased, additional modules and batteries can be added at a later time to expand the system up to its full capacity as required. Where increased autonomy is required several battery cabinets (up to 10) can be piggy-backed onto the basic system using a simple daisy chained inter-cabinet power cables.

8 COMMUNICATIONS OPTIONS Three D-type connectors are fitted on the UPS back panel to facilitate connection to a range of external communication options. The RS232 Interface can be connected to various shutdown and monitoring software applications whereas the Logic Level interfaces are generally used to drive a more simplified remote alarms monitor panel. Shutdown and monitoring Software RS232 Interface Remote Control and Logic Level Interface Four monitoring systems are available for use with the MINIpowerUPS UPS system: WAVEMON can be used for monitoring and automatic shutdown SNMP can be used for monitoring only PowerREPORTER can be used to automatically UPS monitored parameters and alarm events to Uninterruptible Power Supplies Ltd. for appropriate response RELAY INTERFACE BOARD provides volt free contacts for connecting to a remote alarm monitor WAVEMON UPS monitoring software WAVEMON is designed to operate with many of the Uninterruptible Power Supplies Ltd. UPS systems and features both monitoring and automatic server/ups shutdown facilities. The system comprises a bespoke software package which is installed on a local PC and communicates with the UPS over a standard RS232 cable connected to the RS232 port on the UPS back panel. The interconnecting RS232 cable can be up to 15m in length and may be connected/disconnected whilst the UPS is running. The main characteristics of WAVEMON are: On-screen autonomy time/battery time countdown On-screen server log off and shutdown procedure Time and date stamp event log Extensive logging of all UPS activity and power quality data Allow alarm warnings to be monitored remotely via Scheduled UPS service mode and other systems status Graphical user interface for Windows-compatible platforms Automatic unattended local shutdown Special modules for MS-Office software to close and save open documents Compatible with all optional modules like UPSDIALER, SNMP adaptors, temperature sensors, etc. SNMP ADAPTER for network management/remote monitoring Simple Network Management Protocol (SNMP) is a world-wide standardised communication protocol that can be used to monitor any network-connected device via a simple control language. The monitored results are displayed in a web browser. When this facility is used in conjunction with the MINIpowerUPS, an external SNMP adapter is used which is connected to the RS232 connector on the UPS back panel. The SNMP adapter is then connected to the network by means of a standard RJ-45 terminated Ethernet connector, and the UPS-Management software agent installed in the SNMP adapter monitors the UPS operating parameters and outputs its data in SNMP format to the connected network MINIpowerUPS Technical Specification Dated 05/08/14

9 UPS Ethernet Terminal External SNMP Adapter The external SNMP adapter is enclosed in a small box which must be powered from a backed-up supply supported by the UPS output so that its power is maintained in the event of a mains failure. A suitable plug-top power supply is included with the option kit. Note: It is the customer s responsibility to provide a suitable, backed-up mains supply for the adapter. In order to use this adapter the operating system you are using must be SNMP-compatible. We offer our software with SNMP functionality together with NetWare, OS/2, all Windows NT systems on INTEL and ALPHA. The SNMP adapter requires a PC with terminal connections and, for normal operation, at least one Ethernet network connection. PowerREPORTER management software PowerREPORTER is a remote monitoring and management service which is a part of the premium power protection concept. ThePowerREPORTER application: Provides affordable, continuous monitoring over mission-critical facilities and offers peace-of-mind by detecting and warning of any potential system problems before they become a crisis.

10 Logic Level Interface The outputs from the Logic Level Interface (9-pin and 15-pin) connectors are normally used to drive a basic remote alarms panel. The available output signals are shown below: 9-pin 15-pin 1 5 Input ON/OFF (Max. voltage +15V, equivalent to the ON/OFF button on the front control panel) V (max 30mA) 3 3 AUTONOMY RESERVE (active high 15V, max 5mA) 4 2 UPS RUN ON BATTERY (active high 15V, max 5mA) 5 1 GND (common) 6 15 GENERAL ALARM (Open collector active low, max 50mA) 7 14 AUTONOMY RESERVE (Open collector active-low, max 50mA) 8 GND (common) 9 12 UPS RUN ON BATTERY (Open collector active-low, max 50mA) 7 OVERLOAD (Open collector active-low, max 50mA) Relay Interface Board An optional Relay Interface Board is available to act as an interface between the UPS and a remote alarms panel. This option contains three changeover relays that are controlled by the UPS Logic Level outputs to provide volt free signalling to the remote panel. The board is contained in an ABS box which is fitted to the UPS back panel and connected to the 9-pin D-type connector on the back of the UPS by means of the supplied 0.6m ribbon cable. The board s outputs can be wired to provide indication of: UPS on Mains UPS on Battery General UPS fault detected Low battery (UPS has been operating on battery power and the remaining autonomy time is low.) Note: All relay contacts are rated at 150Vdc / 125Vac and 1A. INSTALLATION PLANNING The following guidelines should be taken into account when planning a suitable UPS location and environment. Location considerations summary The UPS equipment must be installed and transported in a upright position. The floor at the installed location and en-route from the off-loading point must be able to safely take the weight of the UPS and battery equipment. The floor material where the UPS is to be located should be non-flammable. Local fire protection standards must be respected. The location must be vibration free. Environmental considerations summary Ensure the humidity (< 90% non-condensing) and temperature (+15 C to +25 C) are within prescribed limits. An ambient temperature of 20 C is recommended to achieve a long battery life. Any prescribed air cooling flow must be available. Ensure the air conditioning system can provide a sufficient amount of air cooling to keep the room at, or below, the maximum desired temperature. Ensure no dust or corrosive/explosive gases are present MINIpowerUPS Technical Specification Dated 05/08/14

11 CLEARANCES Tower cabinets The MINIpowerUPS 5000/10000 UPS Tower cabinet is compact and mounted on wheeled castors so that it can be easily moved to its intended operating location. As shown in the illustration alongside, the UPS and battery cabinets require a minimum of 200 mm clearance at the rear and either side to permit adequate cooling airflow. However, in each case full rear access is required for cabling, and side access is necessary for maintenance and repair. For this reason it is recommended that the cabinets are located so that they can be wheeled forward to provide the necessary side and rear access when required. X BATT. CAB. Front Y* V UPS Front Y* X This recommendation must be taken into consideration when cabling the equipment so that a sufficient cable length is provided to allow for the prescribed cabinet movement. A space of 900 mm is shown at the front of the cabinets. This allows adequate room for the safe passage of personnel during normal operation and also sufficient space for the cabinets to be pulled forward for access, as described above. Ensure that the cabinet is located in an area where the ventilation grills are unlikely to be accidentally covered. Access Space V 200 mm X 200 mm Y* 200 mm Z 900 mm Z Rack-mounted cabinets The MINIpowerUPS Rack-mounted cabinet is designed to fit into a standard 19 inch rack and is 6U high. The cabinet is fitted through the front of the rack, supported on suitable rails and secured in position by means of two screws on each side of the front of the assembly. All MINIpowerUPS 5000 Rack-mounted UPS cabinets contain the UPS batteries; however a matching rack-mounted battery cabinet is available if an extended battery facility is required. Where used, the separate battery cabinet (also 6U) and UPS cabinet should preferably be fitted in the same rack and positioned immediately adjacent to each other. Due to the weight of the assembly it is usual to mount the UPS cabinet in the bottom of the rack and the optional battery cabinet (where used) mounted immediately above it. There is no minimum space requirement above or below the UPS cabinet when it is in-situ, but a minimum of 200mm must be provided at the rear of the unit to allow for adequate cooling air flow and facilitate cabling. As the UPS cabinet is 600mm deep this implies a minimum rack depth of 800mm. As rear access is required for cabling, sufficient space should be provided behind the rack to permit easy passage recommended 900mm. A similar space is required at the front of the rack to enable the UPS cabinet to be handled while it is being installed.

12 UPS POWER CABLING The UPS input and output cables are fitted to a single power connector that plugs into a receptacle located on the rear of the UPS cabinet. A ready-cabled connector of approximately 600mm in length, and terminated with an input plug and outlet socket suitable for the UPS capacity rating, is provided with the equipment. Where a separate battery cabinet is employed a purpose-made cable is also supplied suitable for connecting the battery cabinet to the UPS. Note: The UPS must be installed to prescribed IEC or local regulations (e.g. BS7671:2008). Extended battery cabinet connections Additional battery cabinets can be connected to the UPS system to further extend the available autonomy time. Where an extended battery cabinet is used, the standard cabinet inter-connect cables are replaced by splitter cables that can be effectively daisy chained to connect any number of cabinets together. When several cabinets are connected as shown, the battery charger within the UPS cabinet may inadequate to fully charge all the additional batteries. In this case an independent battery charger is fitted to each extended battery cabinet which must be connected to a mains supply using a standard IEC power cord. A C A B B Standard cable Splitter cable UPS Cabinet Batt. Cab. 1 Batt. Cab. 2 Batt. Cab. 3 Maintenance bypass option A Maintenance Bypass option is available which allows the load equipment to be powered from the raw mains supply when the UPS is totally powered down. Where the option is used, the Maintenance Bypass switch is built into the UPS power connector and requires no modification to the UPS. When the Maintenance Bypass switch is closed, the UPS power connector can be disconnected from the UPS whilst maintaining the (raw) load supply. This allows the completed UPS cabinet to be swapped out for repair if required without disturbing the load supply MINIpowerUPS Technical Specification Dated 05/08/14
